device to the HDMI input of the SY-HD-S41. Connect a HDMI cable from the HDMI output of the SY-HD-S41

Auto Selection Mode

To enable the auto selection mode, press button 1 until the Auto LED lights. In this mode the SY-HD-S41
behaves in the following manner:
1. It will automatically select to the next highest available input whenever the currently selected
input source stops providing an HDMI signal.
2. When a new HDMI signal appears at any input, that input is automatically selected.
3. If the HDMI signal for an input that is not selected stops being provided, the unit will switch to
the first lowest numbered input that has a valid HDMI signal.
Manual selection mode in not possible whilst the Auto LED is lit, to return to manual switching mode you
must press input 1 button for three seconds.
IR Remote Control
The SY-HD-S41 is supplied with a remote control key pad that allows the operator to change the input
selection provided that there is a direct line of sight to the switcher unit. Simply make your selection from
